Nexa Style/Weight Help!

Hello there, I'm wondering if any of the clever graphics folks on here could help me figure out which Nexa style/weight would be best for use on a business card?

The options are shown here: http://www.myfonts.com/fonts/font-fabric/nexa/

I'm drawn to Book or Regular but any advice greatly appreciated

Thank you! :)

Personally, I would go with the heavy for the name of the company (if the name of the company is not a logotype) and the thin or light version for the rest of the text. Heavy against light is an attractive combination.
